Learning project that became my favourite: a chiptune synth written entirely in x86-64 assembly (Linux, NASM). No libc, no audio library — just computing raw 16-bit samples and writing a WAV header by hand.

The premise is that sound is just a list of numbers (44100/second) describing where a speaker sits. So the whole synth is: generate the numbers, write them out.

It does four oscillators (square/saw/triangle + LFSR noise), polyphony by mixing voices into one buffer, ADSR envelopes, and FM synthesis with a hand-built sine table. Working on effects next (vibrato, delay, reverb).

Feedback on the low-level details welcome — especially the fixed-point math in the FM operator.

My attempt at creating a classic hero, inspired by Flash Gordon, The Rocketeer, The Iron Giant, etc.
